摘要：Li ion/Na batteries has shown great promises in various energy related applications. The performance of these energy storage devices can improved with strategized design and preparation of the electrode materials. We carried out works on growth of 2D structured cathode/anode material, including LiMPO4 (M=Fe, Ni, Co, Mn) and MPO4, and few layered black phosphorus by wet chemical processes. This type of materials is typical thin sheet structure with thickness of 2-5 nm and show promising Li/Na storage properties. We also synthesis of few layered black phosphorus nanosheets through diferent methods and study their Li/Na storage properties. Especially, we try to improve their chemical stability by forming composite structures with the aid of spark plasma sintering (SPS) process. It shows that excellent air stabilityof SPS-processed black phosphorus can be achieved over the 60 days observation in maintaining its high Li storage properties.
